Load NZ coastline data

… and convert to sf object.

nztm <- detailed_nz_islands |> st_as_sf()

Marine reserves data

load(file = "data/mr_fiordland.Rdata")

Load strata

strata <- st_read("data/FLD25_Strata.kml")

Reading layer `Strata' from data source 
  `C:\git_projects\fiordland_bruv\data\FLD25_Strata.kml' using driver `KML'
Simple feature collection with 13 features and 2 fields
Geometry type: POLYGON
Dimension:     XYZ
Bounding box:  xmin: 166.3883 ymin: -45.8432 xmax: 167.0177 ymax: -45.47082
z_range:       zmin: 0 zmax: 0
Geodetic CRS:  WGS 84

plot(strata)

Load mark

mark <- png::readPNG("img/mark_blank.png") |> grid::rasterGrob(interpolate=TRUE)

BRUV data

Load from Google Sheet

… and convert to sf object.

fld24 <- read_sheet(
  "https://docs.google.com/spreadsheets/d/1IQfLTiWTQnTGynuF7fUu8htJxKZuIVJw4OK6y9qRfU8",

  st_as_sf(coords = c('Longitude','Latitude'), crs=4326) |> 
  st_join(strata["Name"]) |> 
  filter(Quality %in% c("Good", "OK"))

Write full dataset to csv file (for copying stratum column into BRUVmetadata – actually nah)

✔ Reading from "BRUVmetadata".

✔ Range ''FLD24''.

st_as_s2(): dropping Z and/or M coordinate

Export data for printing

dstrat <- c("DZ1","DZ2","DR2","DZ3","DZ4" )
